Having moved into a new house we needed a new front door and cat flap fitted. Dave was quick to respond, understood our urgency, very professional and brilliant at communicating. The whole transaction went smoothly and he was genuinely really helpful. Would happily recommend!

I used Fortress UPVC the first time to replace windows in my house. The job done was absolutely fantastic and very reasonably priced. Following the great job on the windows I then booked them to replace my front door, again this was completed to a very professional standard and very well priced. Dave's professionalism and knowledge was amazing and I would highly recommend using them.

We spent a few weeks looking for somone to install a new glass panel with a Catflap fitted, and was recomened Fortress in Checkatrade. Dave made the process simple with a quick quote based on my estimated messurments, he came over and took accurit messuments, ordered and fitted once made at the factory, we supplied the cat flap and coffee and now all looks great. Dave is friendly and profsional, made the process simple and we are happy with the results, the cat is also happy she can come and go as she wishes now :D
